I upgraded very recently after using LightBurn for more than a year. I have hundreds of projects under my belt, many have been run many times. Using a tool layer (T1 or T2) used to frame the project, now it appears to use the largest layer for framing, even if that layer is an image (in many cases way bigger than the work area) even if “Apply Mask to Image” has been selected. I have tried reading all the older posts mentioning this issue, but all I get is “it is something you have done or didn’t do” or it works as expected. I have not changed a thing. It worked as I expected it to before the update and now framing can not be used to limit where the laser travels during a project run, it uses the largest layer even if the layer is bigger than the work area. Is there a means of changing framing back to how it worked before the update? If there is no setting to change how it operates to how it used to operate, the frame toggle on the tool layer should be removed. I have hundreds of projects (one offs) that can not be just loaded and run anymore and I need to find a new way to manage framing. If there is no way to change it back to rather way it operated before the “Apply Mask to Image” option might as well be removed as it is nearly worthless. How Lightburn used to work made quick jobs using images and lining up the workpiece for burning super easy. Now - not so much.
In case anyone has this issue I found an OK resolution. Select the image and tool after applying the mask and then select flatten. It removes all the image not in the mask. Not great, but it works well enough. The image is then the same size as the mask. If there are other shapes/layers larger than the tool you will still have to deal with them, but at least this quick fix works well enough you don’t have to learn a whole new way to process images and frame your project on the product to be engraved/cut.
On my install of 1.4.05, flatten still produces a rectangular bounding box around images that rubbber band framing follows. For example, if I have an image on a round coaster that I’ve masked and flattened to fit within the coaster, the corners of the image layer’s bounding box are still used for framing.
I’ve pretty much resigned myself to the idea that I need to get a camera setup. I have a 9-up jig that works well for placement of the coasters but the slate is irregular which means I often have to scale to fit each coaste. Framing the individual coasters while working around the bounding box issue means a lot of guesswork and a little wasted time is involved.
